Magnetic media

Any storage medium that utilizes magnetic patterns to represent information is considered magnetic media. Good examples of a magnetic media and magnetic storage is a floppy diskette and hard drive.

Above is an example of the read/write head inside a hard drive. The electromagnetic write head polarizes sections of the hard drive so it is either North facing up or down to represent either 1 or 0, which is binary and how all computers operate and store data. Once the information has been written to the hard drive it is read by the read head, which detects the polarization of each section of the drive to understand the data that has been written.
